Application iiledTcbruary 13, 1902. Serial No. 93,871. (No model.)

To a/ZZ 1071/0711, it may concern:

Be it known that LVILLIAM MORAN, a citizen of the United States,iesiding at South Norwalk, county of Fairfield, State of Connecticut, have invented a new and useful Ventilating-Tunnel, ot' which the following is a specitication.

My invention has for its object to provide means for Ventilating, more especially removing the smoke and steam of locomotives from, tunnels.

With this end in view my in vention consists in the construction substantially as hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, I have illustrated one form in which I have carried my invention into effect.

Figure lis a cross-section of a tunnel, showing a receiving-pipe in position to receive the smoke and steam from a locomotive and exhaust-pipes ou opposite sides thereof; Fig. 2, a horizontal section of the receiving-pipe, the exhaust-pipe, and oblique connecting-pipes looking in the opposite direction from Fig. l.

A denotes the main portion of the tunnel; B, the receiving-pipe, having a continuous longitudinal slot l0 in its lower side in position to receive smoke and steam as it rises fromalocomotive, and C an exhaust-pipe, one or more of which may be used and which may be located above, around, or on either side of the receiving-pipe. The means used for exhausting pipe C forms no portion of my present invention, any suitable exhaust-fan or means for producing a strong air-current being sufficient for the purpose of my invention. In the form illustrated in Fig. l the receiving-pipe and exhaust-pipes, on opposite sides pipes l2. These walls are used to assist in diverting the smoke and steam into the exhaustpipes.

In Fig. 1 a locomotive is dotted in front elevation in order to illustrate with perfect clearness the position relative thereto of the receiving-pipe in use. Fig. 2 isahorizontal section, the position being as when a locomotive is moving in the direction of the top of the sheet.

In practice the draft from the exhaust pipe or pipes will draw the smoke and steam into the receiving-pipe and outward into the exhaust-pipes, the walls 13 acting as delectors and tending to conduct the smoke and steam into the exhaust-pipes.

Having thus described my invention, I claim- A device of the character described consisting of a receiving-pipehaving a continuous slot in its under side, an exhaust-pipeV contiguous thereto, pipes leading obliquely forward from the receiving-pipe into the exhaustpipe, and vertical walls in the receiving-pipe in line with the forward walls of the oblique pipe and extending to the edge of the slot.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM MORAN.
